Mocap and fluoroscopy for Shoulder3D project

In the context of our project Shoulder3D, we spent a day in radiology to acquire specific data required for the validation of our research methodology. The objective of the project is to develop a new kinematic model to reliably evaluate the three-dimensional motion of the shoulder based on motion capture data. In order to compare the kinematics estimated by our methodology with the real motion of the shoulder bones, we performed a double acquisition. We simultaneously recorded motion capture data using our Vicon system and fluoroscopic images.

As you can see on the pictures below, setting up properly the system in such a confine area and dealing with the occlusions of the fluoroscopic device were the tricky parts of our work!
